To ail whom c'i' may concern;

Be it known that I, Lnsilne P. BELL,

citizen of the United States, and a resident. of Pnulline, in the county oiFQBrien and State of Iowa, have invented certain new (and useful Improvements in Heaters for Internel-Combustion Engines, of whichthe following is n specification.

My invention is on improvement in heat-- ers for internal combustion engines, and has L ior ts object to provide a device of the charocter specihed capable of attachment to the manifold of the engine and inclosing the eX- 'hnnst pipe for deflecting the air surrounding the exhaust pipe and heated thereby downwardly on to the menitoid.

in the drawings: Figure 1 is a front view of an engine provided with the improved heater;

2 and 3 are sections on the lines 2-2 and 8-3, respectively, of Fig. 1, each view looking in the direction of the arrows adjacent to the line;

i is a perspective view of the upper portion or hood of the heater;

Fig. 5 is at similar view of the lower portion or body of the heater;

Fig. 5 is :1 similar View looking at the opposite side;

i 7 a-view similar to Fig. 6, show ing {2, modified arrangement.

The embodiment of the invention shown inFigH l to 6, inclusive, is shown in connection with the exhaust pipe 1 of an internal combustion engine 2 of ordinary type, the heater inciosing it portion of the exhaust pipe 1 and a portion of the inzuiiio'ld 'ihe improved heater comprises at lower section or body and an upper section or hood, the said sections being edjnstohly and detechahly connected together. The lower portion may he formed as shown in Figs. 5 and 3 from a sheet of suitable innteriei cot and bent to form on outer wall 4', end walls 5, a hottom wall 6 and an inner wall 7. The outer wail 4 is divided by 21 vertical out 8 into two portions and the bottom Wall 6 has an opening 5) with which the cm? 8 coininnnicntes, the said opening being adapted to receive the nninihild and permit the pars sage thereof.

The inner wall 6 has flaps 10 at its ends which are bent at :1 right angle to the Wall and ohut the inner faces of the end avails 5. Each section ofthe outer wall -l is notched at its u pper edge and intermediate its ends as tion is notched, as shown the adjacent ends of partially inclosin the some for the purpos indicated at ii, and these notches are adapted to receive the bolts 12 which hold the exhaust pipe to the cngineczisin The upper section or hood 13 has a hooked poi? tion It for engaging over the exhaust pipe, as shown more particularly in Fig. 2, and at its lower edge the said hood or upper secnt 15 and 16, the notches registering with the notches 11 when the sections of the heater are in place. It will be noticed that the notch 15 is of greater length then the notch 16, so that the hook portion ll oi the hood may follow the inclinetion of the exhaust pipe. These notches 15 and 1% are adapted to receive the some bolts 12 that are received in the notches 11, and nuts 17 engage the bolts to hold the casing sections in place.

If desireth the lower section may take the form shown in 7, wherein thesnid section consists of an integral enter wall .18, end walls 19, it hottom wall 20 and a sectional inner wall 21. The Wall 20 has the opening 22 corresponding to the opening i for permitting the passage of the manifold, and the adjacent ends of the sections or the well 21 are spec-ed short for enough to perniit the pnssz ge of the manifold into the opening 22. In the construction of Fig. 4, the sections of the wall at are bent outward to permit the manifold to enter the opening 9, after which they are straightened into substantial nvlineinent.

in either construction t e air which surrounds the exhaust pipe and is heated thereby is held by the hood and is deflected downwardly around the manifoid, to heat the mixture it passes from the carburetor to the engine. it

The improved heater is simple end inexpensive, capabie of application to any engins, and by its use permits a greater amount, of mileage to be made froni the some amountof No chz nges are required in the engine structure.-

I claim: I

1. "in combination with the exhaust pigs and the intake manifold of snin-ternei combustion engine of t}. casing detaehahly connected with the pipe and the menifoid an specifieth said casing being-sectional and consisting of a. lower or body portion en,

gaging); the manifold and a. hood or cover engaging the exhaust nice, the hood being 1 '1 I slate having-e hooheo portion for enge ing over the manifold and having notches at its lower edge for engagement by the bolts securing the exhaust pipe in place, said notches providing adjustment between the sections.

2. A heater for internal combustion engines, consisting of a lower section for engnging the manifold and a hood or cover section for engaging the exhaust pipe, the

10 hood having a portion for hooking over the exhaust pipe and having notches at its lower edge, the lower section having openings l'eglsterlng with the notches and -SA1Cl notches and openings being adapted for en-' gngement by the bolts holding the exhaust 15 pipe in. place.
